||Selective interference reveals dissociation between auditory memory for location and pitch.
Investigated segregation of spatial and non-spatial information processing in the auditory working memory through examining the effects of interfering task-irrelevant tones varying in location or pitch on auditory location and pitch n-back tasks. 12 healthy, right-handed Ss (aged 17-29 yrs), performed spatial and non-spatial auditory 1- and 2-back tasks with and without location or pitch interference. Results indicate that in the 1-back tasks, location interference significantly disrupted location task performance, but pitch interference did not. Pitch interference disrupted pitch task performance, but location interference did not. In the 2-back tasks neither the location nor the pitch task performance was disrupted by the interferences. It is concluded that there is a memory-load dependent segregation in the processing of location and pitch information in neuronal networks engaged in auditory working memory.
